While guidelines recommend retrieval of ≥ 6 lymph nodes to ensure accurate staging, evidence for a therapeutic survival benefit is limited.We retrospectively analyzed 253 consecutive resections for intrahepatic cholangiocarcinoma (iCCA), perihilar cholangiocarcinoma (pCCA), and gallbladder carcinoma (GBC) at a high‑volume hepatobiliary center from a prospectively maintained database (2013-2023). Patients were stratified into no (0 nodes), limited (1-5 nodes), and extended (≥ 6 nodes) LND. Postoperative morbidity, recurrence-free survival (RFS), and overall survival (OS) were assessed with uni- and multivariable models.LND was performed in 47 KW - Biliary tract cancer (Other) KW - Lymphadenectomy (Other) KW - Postoperative morbidity (Other) KW - Recurrence-free survival (Other) KW - Staging accuracy (Other) LB - PUB:(DE-HGF)16 C6 - pmid:41699355 DO - DOI:10.1245/s10434-026-19192-1 UR - https://inrepo02.dkfz.de/record/309938 ER -
